application filed December 20, 1917. Serial No. tutdllilii in pencilSharpeners, and it is a purpose thereof to provide a device of thischaracter which is. of small and compact form, and which is soconstructed that in one ad]ust'- ment of the parts it can be used as asafety fastener or clip to retain a pencil'in a pocket.

' A. further object is to provide a structure in which the adjustmentcan be readily and expeditiously made to adapt the device for use as apencil sharpener or as a safety clip, and in which these adj ustmentswill be held until the parts are manually reset.

" provide a knife vide cutting edges by which a pencil will be"sharpenedandat the opposite end is formed lnto 'a'gripping finger to beused when the while when the parts parts are set for application of thestructure as a safety clip or fastener, the arrangement of the partsbeing such that when the knife member is set for sharpening a pencil,the gripping finger portion is presented for use as a handle no turningthe pencil sharpener, are set for use of the structure as'a safety clipforce is exerted edge'of the pocket to .lilll upon the end forcc 'theclamping finger down against the which ingthe safety. clip thereon isfitted.

-With the above andother ob ects in View, understood from thespecification, drawings, and claims, my invention conslsts in certalnnovel features of construction andcombina- 'tion of parts which will behereinafter more fully set fort In the draWings:- v

Figure'l is aview inelevation of the device of my invention with theparts adjusted for use in sharpening a pencil and illustrating a pencilfitted thereto;

. Fig 2 "is a longitudinal sectional View to an improvement ofthe knifehaving the cutting blade formed in conjunction therewith to the pencilhaw-- which will be in part described, and in part,

is used as a safety clip the through the structure with the parts set asEli sectional View taken "Fig. 8 is a fragmentary detail view showing amodification which might be made in the pencil sharpening member.

ig. 9 is an inverted the sharpening member.

A tubular body 1, which is preferably of a resilient metal and which ismade of a size to receive apencil, is slotted through iongitudinally atone side and adjacent one end as indicated at 2, this end beingpreferably slightly contracted so that fitted through the tubular bodyin the manner*"shown in Fig. 3, frictional bearing will be exertedt'hereagainst and the body portion willhe retained against slipping fromthe pencil-,and against therefromj A combination sharpening and clipmember 3 has a foot ring 4 fitted through a transverse bore formed inthe middle portion thereof and this foot ring 4 is contracted into agroove 5 formed periphorally arohnd the middle portion. of the tubularbody 1 so that the combined sharp-- ener and clip member 3 is pivotallymounted upon the tubular body portion and adjacent the slotted opening 2thereof.

On a sharpening end,'the member 3 is grooved on the inner side so thatcutting edgesnre provided'as indicated at 6, and at t e ren'laining endthe member 3 1s made (smooth and rounded so that user will not be tornor, dai'naged. Slit collars 7 and 8 are mounted around the body portion1 on opposite sides of the foot ring 4, it however being understood thatwhile these slit collars are not set or fixed uponthe body portion, theadherent flexibility there perspective view of as "a pencil is when thedevice clothing of the casual displacement ltd 'Figs. 1 and 2.

of will cause the same to be retained in fixed adjustment upon the bodyportion. The opening of the slit collars is of substantially the samewidth as the width of the slotted opening 2, and when the collars areset in certain adjustments the slotted opening 2 is entirely open andunobstructed, whereas in other adjustments of the slit collars theirwidth is interposed across this slotted opening.

In the use of the device as a safety clip, the slit collar 8 adjusted sothat it does not offer any obstruction under one clip end 9 of themember 3. while the slit collar 7 is turned to bring the body portionthereof beneath the knife end 10 of this member, in which position theslit collar 7 forces the clip end 9 of the member 3 down toward thecollar portion of the body 1.. As has been stated, the body portion 1 ismade of sufficient size that a pencil will be received therein and thenatural resiliency of this body portion will sufiiciently hold thepencil within the bore thereof. \Vhen a pencil is placed within apocket, the clip end 9 of the member 3 will be caught over the top edgeof the pocket to clamp the same against the body portion 1 and inconsequence the device will act as a safety clip or attach to secure thepencil against casual displacement from the pocket.

When the structure is to be used as a penoil sharpener,.the slit collar7 is turned to bring the opening thereof into register with the slottedopening 52 of the body member 1 and then the member 3 is swung to movethe knife end 10 thereof into the bore of the body member or portion 1,it of course being understood that the pencil has been withdrawn fromthe slotted end thereof. Thecollar 7 is now given further turningmovement to bring a solid portion thereof over the outer side of theknife end of the member 3, and the slit collar 8 is adjusted to bear onthe under side of the shoulder 11- provided on the clip end 0 of thismember so that the knife end is thus positively held and forced to beinclined into and toward the open end of the tubular body portion 1,substantially after the manner shown in As a pencil is inserted withinthe unobstructed end of the. body portion and is given turningmowmentafter being brought into contact with-the knife end 10 of the member 3.the cutting edges 6 I will sink into the wood of the pencil and 1nconsequence the same will be cut away to sharpen the pencil.

In Fig. 8 I have shown a slightly modified construction of the knife endof the member 3, and as is here illustrated, the inner side of the knifeend is roughened as indicated at. 12, after the manner of a file or raspso that as a pencil is brought thereagainst and is turned,-l.he wood ofthe pencil aseooa will be cut away and the pencil will be properlysharpened.

From the above it will be seen that l. ha ve. provided a structure whichis made up of comparatively few parts and which could be simply andinexpensively manufactured, but i I do not limit myself to such specificdetails but may resort to any practical modifications falling within thescope of the invention as defined in the appended claims.

I claim:

1. A pencil sharpener including in combination with a tubular bodyportion having a slotted opening formed. in one side thereoftransversely and opening through one end, a. combined sharpening andclip member having a cutting formation at one end thereof, a split ringby which the combined member is pivotally mounted in its middle portionupon the body portion to have the cutting formation thereof over theslotted opening, and slit collars mounted on the body portion onopposite sides of the connection of the split ring therewith.

2. A pencil sharpener comprising the body provided with a slottedopening formed in one side thereof,-a combined sharpener and cli memberpivotally mounted upon said body, said sharpening and clip memberprovided with cutting edges formed upon one face thereof, said cuttingedges adapted to be swung within said slotted opening for contact with apencil extending through said body, and means engaging the under face ofsaid combined sharpener and clip member for locking the same ina swungposition.

3. A sharpener of the clam described comprising a body provided with aslotted opening formed in one side thereof, a combined sharpener andclip member, a securing ring pivotally supporting said sharpener andclip member upon said body. and a plurality of split spaced ringscarried by said body and adapted to have their split portions broughtinto registration with said slotted opening, said combined sharpener andclip member provided with stop portions formed upon the under facethereof adapted to be engaged by one of said split collars for boldingsaid combined sharpener and clip member in a swung and operativeposition.
